I read that I can put some RV antifreeze in the holding tank of my new Thetford, so that it stays usable during the winter, but I can't find the ratio anywhere. Thoughts?

Most RV antifreezes are made to use undiluted, and are rated against freezing to their certain specs. If the antifreeze is cut with water, it's effectivity is reduced. If your travels don't include the very low temps, you may be able to use the products in a diluted form, mixed with the effluent. You could run a few tests in cups mixed with water, at different ratios and temps, to see how the various brands compare.

we have used rv antifreeze to flush the toilet in the winter for several years, in very cold weather (below zero). I put about a gallon of antifreeze in the holding tank, and then use it to flush everytime we use the toilet.

Thanks, ND. I will give it a try.I'm in east TN, so it's not too cold, but we did hit 7 a couple of weeks ago.I just don't want the antifreeze to ruin my new Thetford Curve, but I also do want to be able to use it!
